HCL Workload Automation vs OpenPBS

HCL Workload Automation is software for defining, scheduling, managing, and monitoring critical batch processes. It groups scheduled jobs into job streams and supports dependencies, time constraints, and automatic recovery procedures. Graphical views, embedded analytics, and customizable dashboards help teams follow jobs and streams. Event rules can trigger jobs, respond to prompts, notify users of anomalies, or invoke an external product when conditions occur. Documented integrations include Jira, ServiceNow, RESTful APIs, JSONata, and IBM Robotic Process Automation; HCL says Automation Hub provides over 100 plugins at no additional cost. Tasks can run through local agents, without agents, or through APIs, and the product supports container and hybrid deployments, including Docker, Red Hat OpenShift, and a cloud-native service in a customer-chosen cloud. Pricing is available on request, and HCL advertises a 90-day free trial. From version 10.2, customers need their own WebSphere Application Server Liberty and Db2 licenses to keep using them.

OpenPBS schedules jobs and manages workloads in high-performance computing environments, including clusters, clouds, and supercomputers. Its policy-driven scheduling balances job turnaround time and system utilization while selecting job placements. The system is designed for millions of cores and has been tested beyond 50,000 nodes. A plugin framework provides administration visibility and supports customized extensions. Health checks monitor faults and can mitigate them automatically; the fail-over architecture is designed to avoid a single point of failure and keep jobs running through failures. OpenPBS is self-hosted and free under the AGPL 3.0 open-source license, while PBS Pro is also dual licensed commercially. Public-sector organizations such as academic and research facilities generally choose the open-source license. Community help comes through a volunteer forum, without a guarantee of answers or bug fixes. OpenPBS is integrated into the OpenHPC software stack. The installation guide states that SELinux is not supported, and critical and high security fixes are delivered in the next major release.
